Grey seals (Halichoerus grypus) are the larger of the two seal species found in Iceland, with males growing up to 3 meters (10 feet) long and weighing over 300 kilograms (660 pounds). They have a robust body, an elongated snout, and a coat that ranges from dark gray to lighter shades with mottled patterns. Males tend to have a more pronounced, dog-like profile, while females are smaller and more slender. Grey seals are powerful swimmers and deep divers, capable of reaching depths of over 100 meters (330 feet) in search of fish, squid, and crustaceans. They often haul out on remote rocky islands and coastal shores, especially during breeding season when they give birth to their fluffy white pups.
